| </div> |
| <div class="paragraph"> |
| <p>This section shows you how to set up the logger.</p> |
| </div> |
| <div class="paragraph"> |
| <p>When a node starts, it outputs start-up information to the console, including the information about the configured logging library. Each logging library has its own configuration parameters and should be set up according to its official documentation. Besides library-specific configuration, there is a number of system properties that allow you to tune logging. These properties are presented in the following table.</p> |

| <div class="sectionbody"> |
| <div class="paragraph"> |
| <p>By default, Ignite uses the java.util.logging (JUL) framework. |
| If you start Ignite using the <code>ignite.sh|bat</code> script from the distribution package, Ignite uses <code>$IGNITE_HOME/config/java.util.logging.properties</code> as the default logging configuration file and outputs all messages to log files in the <code>$IGNITE_HOME/work/log</code> directory. |
| You can override the default logging directory by specifying the <code>IGNITE_LOG_DIR</code> system property.</p> |
| </div> |
| <div class="paragraph"> |
| <p>If you use Ignite as a library in your application, the default logging configuration includes only console handler at INFO level. |
| You can provide a custom configuration file via the <code>java.util.logging.config.file</code> system property.</p> |

| <p>Use either Log4j or Log4j2 as the logging framework. To enable it, follow the instructions provided in the corresponding section above.</p> |
| </li> |
| <li> |
| <p>If you use the default configuration file (either <code>ignite-log4j.xml</code> or <code>ignite-log4j2.xml</code>), uncomment the CONSOLE appender.</p> |
| </li> |
| <li> |
| <p>In the log4j configuration file, set the path to the log file. The default location is <code>${IGNITE_HOME}/work/log/ignite.log</code>.</p> |

| <li> |
| <p>If you use <code>ignite.sh</code> to start nodes, specify the <code>-v</code> option.</p> |

| <p>If you start nodes from Java code, use the <code>IGNITE_QUIET=false</code> system variable.</p> |
